See, this is why the debate over man made global warming isn’t over. In order to escape the implication of the Medieval Warming period on the theory of human-caused catastrophic warming, alarmists have insisted it was a localized phenomenon, that is, only Europe warmed quickly without the aid of human carbon spewing, and that the rest of the world remained largely unaffected. But a new study about to be published in Earth, shows that the contrary was true–that there is reliable evidence that the entire planet warmed without our help. From the Daily Mail story:
The scientists studied ikaite crystals from sediment cores drilled off the coast of Antarctica. The sediment layers were deposited over 2,000 years. The scientists were particularly interested in crystals found in layers deposited during the ‘Little Ice Age,’ approximately 300 to 500 years ago, and during the Medieval Warm Period before it.
Both climate events have been documented in Northern Europe, but studies have been inconclusive as to whether the conditions in Northern Europe extended to Antarctica. Lu’s team found that in fact, they did. They were able to deduce this by studying the amount of heavy oxygen isotopes found in the crystals. During cool periods there are lots, during warm periods there aren’t. ‘We showed that the Northern European climate events influenced climate conditions in Antarctica,’ Lu says. ‘More importantly, we are extremely happy to figure out how to get a climate signal out of this peculiar mineral. A new proxy is always welcome when studying past climate changes.’
It was still us. People burned wood to stay warm.
The warming alarmists should welcome the news because it could mean we may not actually be causing the earth to melt, but that the earth warms and cools quickly completely on its own in the natural course of things. But they won’t. They are too ideologically invested in the Appocalypse. Goodness gracious, great balls of fire!
